FOR PASSENGER-CARS.

Patented Apr. 4, 1916.

Application filed January 21, 1915. Serial No. 3,609.

To all whom it may concern Be it known that I, CHARLES H. ANDER- soN, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Push-Button Mechanism for Passenger- Cars; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

,tice to mount the 'tated numerous which is a source 'senger car, 2 the curtain box ,My invention relates to an improvement in push button mechanism for passenger cars.

Heretofore it has been the universal pracpush button contacts dipost capping of the car, the running down from the buttons. With steel car wherein metal side posts and rectlyon the side wire connections frieze to the push construction,

metal capping or pilaster for. the same are employed, trouble frequently results from short circuits. gain the old method of installing the push button mechanism necessiwire connections, each of of possible trouble. 7

The object of my invention is to dispense entirelyvwith wire connections between the push buttons and the wires carrying the current, and employ mechanical means actuated by the pushbutton for closing the clrcuit through thewires carrying the current, the said latter wires being continuous throughout the car and-without any permanentconnection with the; several push buttons, thereby eliminating all trouble caused by defective joints or connections.

In the accompanying drawings, Figure 1 mg my improvement installed therein; Fig. 2 is a view in horizontal section through a side post, showing the metal capping forthe latter and the push button carried by the metal capping, and Fig. 3 is tion of the strip carrying the main wires, and the block carrying the metal finger which connects with said main wire when the push button is actuated.

7 1 represents the metal side is a view in section through a steel car showpost of a pasand 3 a combined metal cap or pilaster and curtain and window frame guide secured to the inner or free edge of the web of the side post.

Located within the curtain box 2 is a wood strip 4, extending throughout the length of a view in sec the car and carrying the wires 5 which are connected up to a battery or other source of electricity and also to the bell. The wires are preferably located within grooves formed in the bottom of a recess extending throughout the length of the strip 4, and are covered and concealed and protected by the strip 6 secured within said recess.

Mounted to move vertically within a slot 1n the edge of the strip 4 a jacent the post 1, is the block 7, made of fiber or any other non-conducting material, and provided with a metal finger 8, which projects into a recess 9 formed in the strip 4, the said wires 5 passing through, and exposed within said recess 9 above the finger 8, so that when the finger iselevated, it will make contact with both wires 5, close the bell circuit, and ring the bell. Theblock 7 preferably terminates at its top in the plane of the strip 4: and is held normally in its depressed position with its finger 8, out of contact with the wires 5, by the spring 10 secured to the top face of closure strip 6 and bearing at its free end against said block. While the employment of the spring is desirable, it is not absolutely necessary, asthe weight of the block 7 and its attached parts is sufiicient to maintain the block in its normal position with its finger 8, out of contact with the wires 5. The

lock is provided with a shoulder 10", which, when the block is in its normal position rests on the base board 11 of the win dow curtain box 2, and is yieldingly held on the same by the spring 10. V

Secured to and depending from the block 7,-is the rod 12 which passes down within the sheet metal cap 3 of post 1, and rests at itslower end on the top ball or sphere 18 of a series which is located within the curved bore of elbow 14C. The lower end of said rod 12 projects into the upper end of said elbow a distance greater than it is moved vertically to carry finger 8 into contact with the wires 5, hence there is no possibility of dislodging the rod 12 by any movement that can be imparted to the push button. The elbow is clamped to the post cap or pllaster 3 by the screw sleeve 15, which is screwed onto the exposed end of the elbow, which as shown projects through a hole in the cap or pilaster, and not only operates to lock the elbow in place, but also locks the push button 16 to the elbow with the finger 17 of the button in line with the lower ball of the series of balls. The weight of the block 7, rod 12 and balls circuiting.

13 normally hold 'the button 16 projected,

and when the latter is pushed in to elevate the rod 12, it will return jected position as soon as moved from the same.

\Vhile it not necessary that the rod 12 shall be attached to block 7, I prefer to so construct it, as there will then be no lost motion between the parts.

From the foregoing it will be seen that by pushing in on the button 16, the balls will beforced up the bore of the elbow and impart a lifting movement to the rod 12, which in turn lifts the block Tuntil the finger 8 of the latter makes contact with the wires 5 the pressure is rethus closing the circuit and ringing the bell.

By releasing the pressure on the button, the parts will drop back into normal position,

and will be assisted in such movement by the,

spring '10.

' With myrconstruction the wires carrying the current are continuous from end to end of. the car without any permanent connection with any of the push buttons, thus eliminating at least four joints for each push button and minimizing all chance for short It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction shown and described, but

Having fully described my invention what- I claim as new and desire to secure by Letters Patent, 1s:-
